Dear R-list

I have a dataset like below (points), how can I produce a max value for each column. I need a result like (I hope my eye correct):

       [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12]

[1,] 21 1 10 99 14 19 6 9 5 8 5 7

This is a small dataset from 10000 row.
 > points

       [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12]

[1,] 21 0 9 16 1 11 5 2 5 8 2 5
[2,] 19 1 10 93 7 0 0 4 1 6 5 1
[3,] 13 0 4 30 5 7 1 1 5 6 3 6
[4,] 5 1 9 61 6 19 2 9 5 1 1 6
[5,] 2 1 1 99 1 18 1 3 2 8 1 2
[6,] 7 0 5 45 14 4 6 5 1 6 5 6
[7,] 0 0 6 89 14 3 2 0 3 7 2 6
[8,] 15 0 1 30 14 17 3 2 3 3 3 5
[9,] 14 0 5 28 8 10 1 6 5 2 3 6
[10,] 12 1 4 65 6 2 4 1 4 4 4 7 [11,] 14 1 1 3 12 10 5 7 4 3 3 4 [12,] 15 0 1 55 7 7 1 5 3 7 0 2 [13,] 14 0 5 4 7 11 2 0 4 2 2 3 [14,] 13 0 6 94 6 2 4 9 3 4 0 3 [15,] 21 1 5 79 14 14 6 3 5 6 5 6
